Answer:
He had $36 in the beginning
Step-by-step explanation:
We are asked to calculate how much John has after making some series of purchases. Let’s proceed.
Now, let the initial amount of money John had be $X. Let’s keep this
He initially spends 2/3 at a bookstore, the fraction unspent is 1/3. Since x is our figure, the amount unspent is $x/3
Now, he spent 1/3 of this at a craft store. This means he didn’t spend 2/3 of this and it corresponds to $8.
This mathematically means:
2/3 * $x/3 = $8
2x/9 = $8
2x = $72
x = $72/2 = $36
Answer:
-8
Step-by-step explanation:
It's basically -4-4. Which means -(4+4) = -8.
Answer:
Step-by-step explanation:
P(A|B)=P(A)
conditioning on one does not effect the probability of the other as they are independent
